whats weird is (for me) indicas are generally to blame if i get a panic attack while smoking.

sativas (all though considered to be an up high) relax me as they put me in a positive mood that doesnt let me have my mind dwell on the bad things.

this is just experience though.

i think what does it for me is the body highs make me nervous esepcially if i smoked too much or am not in a good mood to begin with...

sativas are more of a clear high and i like it better...

so i think it matters on the TYPE of indica or sativa...because there are pure indicas that dont effect me negatively.
